Free Speed Tree model Leaves not showing up in Package?

Two images here. i’m using the free Speed Tree models. You get 4 free off of the site…I’ve just now jumped into Speed tree and I was seeing how they work.
The Desktop Tree leaves are not showing up in the package…I really didn’t have to do anything to to models once they were put in the project.

Can someone tell me if it’s something I’'m doing wrong?

PS. I see an image on the HUD missing too…
I think that’s because It’s not a power of 2…

Can someone please help ??? I really don’t understand what’s happening here. I don’t even know what to check.

I wouldn’t call this completely solving the problem but I did realize that the one tree that wasn’t loading correctly was a mobile tree. The fact that it was packaged for windows may have been the problem. I’m not sure where those decisions get made if they do. But I scrapped that one tree…and for now problem solved.

Thanks!
